OPENER FOR TINS OR THE LIKE CONTAINERS.

Application filed March 4, 1927, Serial No. 172,798, and in Czechoslovakia December 22, 1926.

This invention concerns an improved opener, for tins or the like containers, of the type rotatably mounted on one part of the container and adapted on rotation to lift the 5 lid or cover thereof.

In a known arrangement the opener is journalled in a U shaped strip of metal Welded or soldered at both its ends to the tin. Such an opener consists, therefore, of three 10 parts, namely the opener proper, a rivet and the U shaped mounting. Prior to the welding or soldering these three parts have to be riveted together, it being necessary to dispose the opener at right angles to the mounting, so as to render the parts to be soldered accessible.

In the opener according to the present invention the hollow rivet or the like on which the opener is pivoted is welded, preferably at one point, directly to the container.

An opener according to this invention is illustrated by way of example in the drawing in a sectional view perpendicular to the axis of the tin.

Referring to the drawing a tin opener a, which in plan view is preferably lever-shaped and in section may be of any desired shape, is mounted on a. hollow rivet 7) in such a manner as to be capable of rotating freely on the latter. The said rivet is welded at one point at the centre to the wall or" the tin c, preterably by electrical Welding. To ensure the welding of the opener at exactly the desired spot, a recess d is preferably pressed beforehand in the wall of the tin.

The head of the rivet b is inserted in this recess prior to the welding, its exact positioning b eing thus greatly facilitated and possible displacement before or during welding avoided.

be seen that the opener according It will to the inascertained the nature of my said invention and in whatmanner the same is to be performed, I declare that what I claim -1. In combination, a metal container havlng a 11d, an opener therei'or, comprising a cam for engaging an edge of said pivot rotatably attached to said pivot having a fiat base and said having an allocating recess receiving said lid, and a cam, said contamer base, said pivot being welded to the outside of the container within said recess.

2. A lid opener for friction lid containers oi the type in which the lid tightly telescopes over the sides of the container, comprising a unitary device including a cam for engaging the edge of the 11d and a pivot rotatably at tached to said cam, said pivot l121'\ welded to the side of the container lid.

ing a flat base torming a surjliace adapted to be spot below the Signed at Prague, Czechoslovakia, this 15th day of February, A. D. 1927.
